LUBRICATING METHOD AND APPARATUS Fild March so, 1929 z sheets-sheet 2 plate H, and this pipe is clamped to the removable plate H by means of nuts 13. The

portion of the pipe or conduit 11 extending to the exterior of the plate H is connected by another pipe or tube with the intake inani- Afold-E. Y i

In order j to guide the lubricant which splashesfagainst a face of the 'sector-shaped plate 10-to the bore orl openingl 16 inthe pipe 11, this plate ispreterably provided at one of its radial edges with'a angeor, trough 17 l. which may be formed integral with the plate V10. The lower end of thisflaiige extends into proximity in the opening 16 inthe'conduit 11 .and is preferably provided'witha curved i part' 17a which serves to 'guide lubricant. into -the 4bore 16.V Consequently any lubricant which flows down along the flange or trough ,fl'i's guided to the-bore vo rlopening 16 and is consequently drawn through the tubes ll'and 15 into the-.intake manifol'dE.- i

about .the axis 'of the' mbe' so ythat the 'plate 10 may occupy various' angular relations. When the plate is arranged asl-shown in Fig.

Y 4,7 it willbe obvious that lubricant from only approximately one-halffoftheplate will pass downwardly along the aange ,im `the @par ing 16 and the tube 11.

7 j If the lubricant receiving plate in thisposition does not supply suiiicient lubricantlto vproperly lubricate the upper ends of the cyl-H inders and ofthe valve stems,the yplate may beswung to the right so that larger portion .of the ,plate is arranged,verticallyover the flange 17. Consequently a larger quantity 'lof'lubr'icant will bedelivere'd tothe opening `in the pipe 11. Similarly 'if a vlesser quantity oflubricant is desired, the plate maybe swung Y to thev left of theposition shown in Fig. 4' so that a small surface of the plate 10 lies vertically'above the. flange 17. When these lubricant controlling plates are applied to .cars of a standard make,the'adjustrnent ofthe plate Y about the axis is not necessary,`since the plate inay be initially lset into 'a predeterminedposition which isknow'n toprovide the desired amount of lubricant; i

In addition to controlling the supply of lubricantby adjusting the lubricant receiving platel'() abouttheaxis of the,` pipe 11, itv

may be desirable also to restrict the passage to; the' intake manifold. This may be done,

as in thefconstruction.illustrated, 'byv provid- Y ing .a restriction in the tube 11 inthe orindoiiV 'a sleeve 18, the outer surface V of k'whichinay and this sleeve` has a jet opening 19 therein oi the sizedesired to provide the' necessary .amount of lubrication to theintake manifold."
